SHOCK-LOADER.

Specification of Letters IPatent.

Patented Aug. 13, 1907'.

Application filed January 14,1907. Serial No. 352,253.

To all whom it may concern: d

Be it known that l, WILFRID PELTIER, a citizen of the United States, residing at Concordia, in the county of Cloud and State ol' Kansas, have invented a new and useful Shock-Loader, of which the following is a specification. I

This invention has reference to improvements in i shock loaders, and while not entirely confined thereto has more especial reference to the picker located at the front of the machine and designed to catch the shocks from the ground and lift them on to an eleva-l tor which, in turn, deposits them upon an apron to v trollable to disengage from the shock prior to the deposition of the same uponthe elevator apron and also being provided with means whereby, should the picker blades engage an obstruction, they will yield to said' obstruction and no harm will come therefrom tothe machine.

The invention-will'be more fully understood byl reference to the following specification, taken in connection with the accompanying' drawings, in which,'-

Figure 1 is a plan view, with parts broken away, of

the improved shock loader; Fig. 2 is a side elevation of the same; Fig. 3 is an enlargedlsectional detail view of the picker showing' one of the operating cams; Fig. 4 is a sectional view of the picker showing the action of the blades under the control of the cam g Figs. 5 and 6 are detail perspective views of the picker shaft and contiguous parts.

Referring to the drawings, there is shown a main frame 1 mounted near the rear upon the drive wheels 2 and near the front upon caster wheels 3. At the front of the machine the framework is continued laterally outward from each side member of the frame, as shown at 4, -to which are attached the whiiiletrees 5 connected one to the other through a chain or rope `G passing around pulleys 7 mounted on the side bars of the frame ata point to the rear of the caster wheels. equalizer is shown only tentatively and need not be further described. i

The drive wheels 2 may each be provided with a oneway automatic clutch by whichthey are coupled fto the axle 8, but as this clutch forms no part of 'the present invention it is not shown.

Upon the axle S is secured a lgear wheel 9 meshing with a pinion 10 fast on a short counter-shaft 11 journaled in boxes 12 upon the framework parallel with the axle S. One end of this shaft carries a sprocket wheel 13 and the other end a beveled pinion 14. The sprocket wheel 13 is coupled by means of a sprocket chain 15 to a sprocket wheel 1G upon a short shaft 17 V'carrying two other sprocket wheels 1S-'19.

This draftv The sprocket wheel 18 is coupled by a sprocket chain 20 to a sprocket wheel 21 upon a shaft 22,` which latter is extended across the framework near the front end thereof, being mounted in suitable bearings, and this shaft 22 is' provided with suitable supports and driving means for a slat conveyer 23 extending to the forward end of the machine where it is provided with suitable supports mounted upon another shaft 24 extending across the machine contiguous to the picker there located and to be hereinafter described. The shaft 22 also carries a sprocket wheel 25 which, through a sprocket chain 2G, conveys power to the picker in a manner to be hereinafter described.

Y Returningvnow to the shaft 1G receiving power from the drive wheels, the sprocket wheel 19 thereon is connected by asprocket chain 27 to another sprocket wheel 2S mounted ona shaft 29 extending across an upwardly-extending portion of the` framework and carrying supporting and propelling means for the lifting slat conveyer 3() which is designed to receive and elevate the shocks received on the conveyer 23 to the highest point of the machine.

Extending laterally across the rear of the machine upon the framework thereof and elevated to a point a little below the upper end ofthe conveyer 30 is a laterally-traveling slat conveyer 31 mounted at its two ends upon shafts 32A- 33 and driven by sprocket chains 34 engaging sprocket wheels 35. The shaft 3? has a sprocket wheel 35 drivenvby a sprocket chain 3G receiving motion from a sprocket wheel 37 on one end of a shaft 38 journaled in the lower rear portion of.the frame 1 and carrying at its other end a beveled pinion 39 meshing with` the pinion 14 before mentioned. The outer end 40 of the slat conveyer 31 is capable of having its extreme outer end adjusted through an arc by any appropriate means as through the side links 41, and take-up mechanism consisting of the sprocket wheel 42 on-an arm 43 controlled by the spring 44 is provided for thesprocket chains 34.

The structure so far described is so formed that when the machine is drawn forward and the drive wheels 2 are rotated, the various conveyer-s are moved at proper rates of speed to carry the shocks received on the conveyer 23 up by the conveyer 30 to the conveyer 31, from whence they pass to the part 40 and fall from the outer end thereof upon a wagon suitably -placed to receive them.

Coming, now, to the picker which is designed to lift the shocks from the ground and deposit them upon the first conveyer 23, this picker consists of a cylindrical body portion 45 fast upon a shaft 46 which extends' across the front of the machine and is journaled in boxes 47 adjustable lengthwise in the front end of the' adjustable lengthwise in the front el the lrame ol the machine. Upon one end of the shaft 46 there is secured a sprocket wheel 48 receiving motion by the sprocket chain 26 before referred to.A At diametrically opposite points near each end ol the cylindrical body there are journal bearings 49 for rock shafts 50 each carrying the picker lingers or blades 5l, which may be of the general shape shown in the drawings or may be simply lingers. Upon each end of the rock shalts 50 'is a collar 52 having on one side a lug 53 land this collar is made fast upon the'shalt 50 in any suitable manner. Mounted upon each end ol the shalt 50 between the collar 52 and the picker blades 5l is a sleeve 54 on one side ol which is formed a projecting member 55 terminating in a stud 56 parallel with but removed a distance lrom the respective shalt 50. The lug 53 is provided with an aperture 57 and the member 55 is provided with a slot 58 in line with the aperture 57 lor a purpose which will hereinalter appear.

Upon each stud 56 is journalcd a roller 59 engaging in a cam groove 60 upon a iiXed cam plate 6l last on each side ol the lrame l at its lront in position to be engaged by the rollers 59. This cam plate 6l may lorm part ol the bearings ol the shalt 46 and be adjustable therewith. The iront hall ol the cam groove 60 is concentric with the axis ol the shalt 46, while the rear half is made on a longer radius, so that when the roller 59 reaches this portion ol the groove it will be drawn toward the shalt 46 in the manner clearly indicated in Fig. 3.

Secured to the lug 53 by being passed through the aperture 57 therein and riveted or otherwise secured to the said lug is a curved rod 62, the curvature being struck lrom the axis ol the rock shalt 50. This rod passes through the slot 5S in the member 55 and is surrounded by a helical spring 63. This spring bears at one end against the member 55 and at the other end is adjustably held by a nut 64 screwed upon the threaded end of said rod 62. When the roller 59 is within the portion 0l the groove 60 concentric with the shalt 46 the blades 5l are held in a radial position projecting outwardly lrom the cylindrical body portieri 45 ol the picker. When the rollers reach the latter portion oi the groove they are drawn toward the shalt 46 and the rock shafts 50 are rotated in their bearings to bring the blades 5l up to the cylindrical portion 45 of the picker.

Suppose, now, that one of the picker blades in passing near the ground should encounter an obstruction. The spring 63 will immediately yield and allow the blade to trail over the obstruction without harm to any portion ol the structure. This is an important leature of my invention and enables me to use the machine without danger where otherwise it might become irreparably injured.
